Codemap

Query your codebase. Codemap builds a local SQLite index of structural metadata (symbols, imports, exports, components, dependencies, CSS tokens, markers, and more) so AI agents and tools can answer “where / what / who” questions with SQL instead of scanning the whole tree.

• Not full-text search or grep on arbitrary strings — use those when you need raw file-body search.
• Is a fast, token-efficient way to navigate structure: definitions, imports, dependency direction, components, and other extracted facts.

Documentation: docs/README.md is the hub (topic index + single-source rules). Topics: architecture, agents (codemap agents init), benchmark, golden queries, packaging, roadmap, why Codemap. Bundled rules/skills: .agents/rules/, .agents/skills/codemap/SKILL.md. Consumers: .github/CONTRIBUTING.md.

Install

bun add @stainless-code/codemap
# or: npm install @stainless-code/codemap

Engines: Node ^20.19.0 || >=22.12.0 and/or Bun >=1.0.0 — see package.json and docs/packaging.md.

CLI

• Installed package: codemap, bunx @stainless-code/codemap, or node node_modules/@stainless-code/codemap/dist/index.mjs
• This repo (dev): bun src/index.ts (same flags)

# Index project root (optional codemap.config.ts / codemap.config.json)
codemap

# Version (also: codemap --version, codemap -V)
codemap version

# Full rebuild
codemap --full

# SQL against the index (after at least one index run). Bundled agent rules/skills use --json first; omit it for console.table in a terminal.
codemap query --json "SELECT name, file_path FROM symbols LIMIT 10"
# With --json: JSON array on success; {"error":"..."} on stdout for bad SQL, DB open, or query bootstrap (config/resolver)
codemap query "SELECT name, file_path FROM symbols LIMIT 10"
# Query is not row-capped — add LIMIT in SQL for large selects
# Bundled SQL (same as skill examples): fan-out rankings
codemap query --json --recipe fan-out
codemap query --json --recipe fan-out-sample
# List bundled recipes as JSON, or print one recipe's SQL (no DB required)
codemap query --recipes-json
codemap query --print-sql fan-out
# `components-by-hooks` ranks by hook count without SQLite JSON1 (comma-based count on the stored JSON array).

# Another project
codemap --root /path/to/repo --full

# Explicit config
codemap --config /path/to/codemap.config.json --full

# Re-index only given paths (relative to project root)
codemap --files src/a.ts src/b.tsx

# Scaffold .agents/ from bundled templates — full matrix: docs/agents.md
codemap agents init
codemap agents init --force
codemap agents init --interactive   # -i; IDE wiring + symlink vs copy

Environment / flags: --root overrides CODEMAP_ROOT / CODEMAP_TEST_BENCH, then process.cwd(). Indexing a project outside this clone: docs/benchmark.md § Indexing another project.

Configuration: optional codemap.config.ts (default export object or async factory) or codemap.config.json. Shape: codemap.config.example.json. Runtime validation (Zod, strict keys) and API surface: docs/architecture.md § User config. When developing inside this repo you can use defineConfig from @stainless-code/codemap or ./src/config. If you set include, it replaces the default glob list entirely.

Programmatic API (ESM)

import { createCodemap } from "@stainless-code/codemap";

const cm = await createCodemap({ root: "/path/to/repo" });
await cm.index({ mode: "incremental" });
await cm.index({ mode: "full" });
await cm.index({ mode: "files", files: ["src/a.ts"] });
await cm.index({ quiet: true });

const rows = cm.query("SELECT name FROM symbols LIMIT 5");

createCodemap configures a process-global runtime (initCodemap); only one active project per process is supported. Advanced: runCodemapIndex for an open DB handle. Module layout: docs/architecture.md § Layering.

Development

Tooling: Oxfmt, Oxlint, tsgo (@typescript/native-preview).

| Command | Purpose | | ------------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | bun run dev | Run the CLI from source (same as bun src/index.ts) | | bun run check | Build, format check, lint, tests, typecheck — run before pushing | | bun run fix | Apply lint fixes, then format | | bun run test / bun run typecheck | Focused checks | | bun run test:golden | SQL snapshot regression on fixtures/minimal (included in check) | | bun run test:golden:external | Tier B: local tree via CODEMAP_* / --root (not in default check) | | bun run benchmark:query | Compare console.table vs --json stdout size (needs local .codemap.db; docs/benchmark.md § Query stdout) | | bun run qa:external | Index + sanity checks + benchmark on CODEMAP_ROOT / CODEMAP_TEST_BENCH |

bun install
bun run check    # build + format:check + lint + test + typecheck
bun run fix      # oxlint --fix, then oxfmt

Readability & DX: Prefer clear names and small functions; keep JSDoc on public exports. .github/CONTRIBUTING.md has contributor workflow and conventions.

Benchmark

Use a real project path (the repo must exist on disk). See docs/benchmark.md § Indexing another project.

CODEMAP_ROOT=/absolute/path/to/indexed-repo bun src/benchmark.ts

Optional CODEMAP_BENCHMARK_CONFIG for repo-specific scenarios: docs/benchmark.md § Custom scenarios.

To compare query stdout size (console.table vs --json) on an existing index, see docs/benchmark.md § Query stdout (bun run benchmark:query).
